Set of 31 mm diameter Baader LRGB filters optimized for CMOS
This new generation of Baader CMOS filters features:
- CMOS-optimized Baader filters
- Higher contrast, combined with typical CMOS quantum efficiency and s/n ratio
- Reflex-Blocker™ coatings, for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
- Filter thickness identical to existing standards, with extreme care for parafocality
- Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the telescope side, to additionally eliminate any reflections due to light falling on the edge of a filter
- Each filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
- Life-Coat ™: increasingly hard coatings to allow for a coating that will not age for life, even in the harshest environment
General Features:
- Baader LRGB 31mm x 2mm bandpass filter set, suitable from f/15 to f/1.8
- Anti-reflective RGB filter (red / green / blue) with extremely high transmission of the respective color channel, simultaneously reducing stray light and reflections to an unprecedented level
- Including UV / IR cut-off (L-filter) with 98% transmission over the entire visible spectrum from 420 to 685 nm
- Balanced RGB design allows taking subframes with the same exposure time, which is extremely important for automated imaging tasks.
- Reflex-Blocker ™ hard-coated and planoptically polished, with sealed coating edges (Life-Coat ™)
- Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the telescope side
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
